"I have a 20 gallon freshwater aquarium. I have one golden snail that I bought 3 weeks ago. I have also purchased 2 real plants some time ago. My problem is, I keep getting all these baby snails. So far I have taken out at least 30 babies and deposited them in the garbage. I know that snails can produce babies from a single snail. How do I get rid of them for good! Thanks, Lorraine"
